Russell, who won 11 NBA championships with the Boston Celtics, joined NFL Hall of Fame running back Jim Brown during a panel discussion Wednesday at the Lyndon B. Johnson Presidential Library in Austin. The library is hosing events celebrating the 50th anniversary of the Civil Rights Act.

Russell says questions about whether gay athletes can be good teammates or might disrupt locker rooms are the same questions that black athletes heard back then.
